Copper Cable: Sector shaped conductors 4 x 70mm2 flexible and stranded.

When an electric current flows in a suitably shaped conductor at radio frequencies radio waves can be generated.

Arcing horns are not to be confused with grading rings, which are ring shaped conductors surrounding the high potential end of an insulator string on some high voltage transmission lines, attached to the line.

Thus, the work of many researchers enabled the use of electronics to convert signals into high frequency oscillating currents, and via suitably shaped conductors, electricity permits the transmission and reception of these signals via radio waves over very long distances.
